Description of the Invention (/) The present invention relates to a polyester fiber and / or filament containing a small amount of additives, and a method for manufacturing the same. It is known that polyester fibers and / or filaments containing a small amount of additives are melt-spun according to the composition of the mixture. Generally, at the same spinning speed, the elongation at break of undrawn yarn can be increased. European Patent No. 0, 〇47,464 B1 has taught polymethyl methacrylate ( Polymethyl methacrylate (hereinafter abbreviated as PMMA) is mainly used to increase the elongation at break at higher spinning speeds. This document describes the use of non-agglomerated substances mixed in a molten state, the non-agglomerated substances comprising polyesters of polymethyl methacrylate additives. This step is an optimized premixing step to achieve homogenous products. However, as disclosed in European Patent No. 0,047,464 B1, when high molecular weight PMMA is used as an additive, problems occur in the spinning process (see lines 5 to 11 on page 5). European Patent No. 0,631,638 B1, like European Patent No. 0,047,464 B1, has also described that polymethyl methacrylate has a limited spinning capacity. European Patent No. 0,631,638 B1 describes a fiber polymer containing 0.1-5 wt%, which has 50-90% thioimidized polyalkyl methacrylate relative to the fiber polymer, and is basically an inclusion (inclusion). However, the thioimidized polyalkylmethacrylate additive has a great disadvantage in that the additive has a high price point. The cost of the thioimidized polyalkyl methacrylate additive shows that the required additive manufacturing process is not economical. In addition, the required additives cannot be manufactured in large quantities. 4 --------------- Pack-(Please read the phonetic on the back?

Description of invention (7) Manufacturing. As mentioned above, another disadvantage is that it is limited to spinning safety. When this substance is used as an additive, fiber breakage will occur more often. European Patent No. 0,047,464 B1 discloses that the maximum molecular weight of polymethyl methacrylate is 16,000 g / mole (see Table 5 on page 9). Furthermore, European Patent No. 0,047,464B1 mentioned that the diameter of PMMA exceeds 1 μm in the polyester medium, such an increase makes the elongation at break no longer optimized. Otherwise, the configuration of this inclusion will not be discussed further. As described in European Patent No. 0,047,464B1 and the Greenville 1998 HP5 Highest Economic Polyester Process Fiber Manufacturing Conference, for example in unoriented polyester yarn balls Unacceptable inclusions appeared, that is, non-directionally fused fibers extruded in a ball or drop form by a spinning machine. In European Patent No. 0,047,464B1, lines 4 to 13 on pages 4 and lines 8 and 9 on page 5 have disclosed that inclusions (similar to spherical bearings) in the fiber direction may cause a "rolling effect" This will cause delayed deformation of the polyester. However, in the non-directional polyester yarn ball, the type and size of the inclusions are related to the type and nature of the final product required, and the important spinning behavior that is practically useful to the industry. The above results have not been confirmed. . Therefore, the object of the present invention is to provide a polyester fiber and a filament that make the polymerizable mixture usable, which contains no more than 4% of additives, and can be well-spun, so that the manufacturing method is limited by a small amount. Additives make the additives have a large availability, and because of the large increase in elongation at break, it has a higher economic value. 5 This paper size is in accordance with Chinese National Standard (CNS) A4 (21〇x 297mm) --------------- Installing i — (Please read the notes on the back first to write this page ) ¾. 490513 A7 5280pif.doc / 008 B7 V. Description of the invention (θ) The above-mentioned object can be achieved by the fiber and / or filament of the present invention and its manufacturing method. The present invention provides a fiber and a fibril, which mainly include polyethylene terephthalate as a fiber-forming polymer, and is characterized in that the fiber and the fibril include polymethacrylic acid relative to the fiber-forming polymer 0 Methyl esters, polymethyl methacrylates have an average molecular weight between about 20,000 and 200,000 g / mole, mainly in the form of rod-like inclusions, which are not melt-spun in the forward direction of the extruder extruded by the spinning machine. The measurement is performed under the condition that the lateral particle size of the rod-like inclusion body of polymethyl methacrylate is less than 800 nm, and the spinning speed of the spinning fiber is as high as 8000 m / min when manufacturing fibers and filaments. . In addition, the present invention provides a method for manufacturing a melt-spun fiber or filament comprising polyethylene terephthalate as a fiber-forming polymer, which is first polymerized or melted by condensation. After the fiber-polymer-forming melting step, melt-spinning is performed. The method includes mixing the fiber-forming polymer before performing the melt-spinning and dispersing the second polymer in the fiber-forming polymer that disperses the non-directionally fused fibers And a second polymer at 0.1-4 wt% relative to the fiber-forming polymer, which essentially comprises polymethyl methacrylate having an average molecular weight between about 20,000 and 200,000 g / mol During the spinning process, the spinning speed of the fiber is set as high as 8000 m / min, and the non-directional fiber inclusions extruded through the extruder to obtain a rod-like second polymer inclusion having a lateral particle size of less than 800 nm. 6 This paper size is applicable to China National Standard (CNS) A4 specification (210 X 297 mm) -------------- Loading --- (Please read the notes on the back first to write this page) Order ·-· Line-Printed by the Employees 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 490513 A7 5280pif.doc / 008 R7 V. Description of the invention (4) Brief description of the drawings Figure 1, Figures 2 and 3 show cross-sectional image views of REM of a fused fiber of a dielectric polymer (PET) according to the present invention. The preferred embodiment is surprising, and we have found that fibers and filaments that can be made from polymer blends of polyesters, especially polyethylene terephthalate (PET) and polymethacrylate with small amounts of additives Methyl acrylate, even at high spinning speeds, can simultaneously exhibit a very high elongation at break and outstanding spinning behavior. We thoroughly understand the effects of polyester blends, such as the blend of PET with polymethyl methacrylate, and polymethyl methacrylate, on the increase in elongation at break. We also know the tendency of fibers to break when such blends are spun. Such fiber breaks tend to occur when polymethyl methacrylate having a very high molecular weight is used. Thus, as mentioned above, European Patent No. 0,047,464 B1 described that although the increase in the molecular weight of polymethyl methacrylate causes the effect of the increase in elongation at break to increase, problems in spinning also occur at the same time. In other words, as taught in the conventional art, due to the tendency of growing fibers to break, the strengthening effect of high molecular weight polymethyl methacrylate, which increases the amount of elongation, may be unacceptable. Thus, based on the manufacturing method described in European Patent No. 〇47,464 B1, its economic feasibility is therefore limited. Surprisingly, we found that the present invention uses additives to disperse still-unoriented polyester yarn balls, which does not look like European Patent No. 0,047,464 B1 and Greenwich (1998) GreenVille), as described in the HP5 Highest Economic Polyester POY Process Fiber Manufacturing Conference, has paper-like paper standards that apply Chinese National Standard (CNS) A4 specifications (210 X 297 mm) --------- ------ Install i I (please read the note on the back to write this page) Order · • Line. 490513 5280pif.doc / 008 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs ) Shape or spheroidal shape, but as shown in Figure 1, Figure 2 and Figure 3, a new shape with a rod-like or insect-like shape is stretched. Therefore, the present invention PMMA inclusions with new characteristic structures are described in the examples, especially at very high PMMA molecular weights, which can improve spinning capacity. It should be noted here that the lateral diameter of the new rod-like structure is very In the embodiment, the rod-like inclusions have, for example, a lateral diameter of about 300-400 nm, which is Measure the non-directionally fused fibers extruded by the spinning machine, so-called yarn balls. Importantly, the diameter can be less than 800 nm. It is preferably less than 600 nm, and most preferably less than 400 nm. However, The polymethyl methacrylate inclusions of the present invention having a rod-like structure with non-directional polyester media are not the same as those observed in European Patent No. 0,047,464 B1. The rod-like structure must generally observe different The mechanism described in European Patent No. 〇47,464 B1. And in this paper, it is likely to be the reason for the best Yossi behavior. Thus, the polymer medium has a drop-like or spherical-like bag The body can reduce the effect of orientation, and because the desired molecular motion of the polyester medium is perpendicular to the direction of fiber stretching, the spinning process may have more or less dispersion. It is similar to the first discovery of the present invention. In the case of rod-shaped inclusions, the dispersion of polyester molecules across the fiber should be reduced, which is why the spinning behavior is improved. The present invention includes a polymerized mixture of PMMA at high spinning speeds 8 ---- ---------- install-(please first Read the note on the back and write this page) Order and line!

Description of the Invention (&) Spinning does not occur, for example, with the diffusion of conventional air flowing laterally. However, another well-known and suitable cooling device, such as fast spinning fibers or arrays of fibers by air The air diffuser in the center of the beam applies suction and is used for passive cooling equipment. Generally, the present invention is applicable to the manufacture of partially oriented yarns (POY) (as explained in the examples) and fiber products (such as staple fibers). The industry also discussed the situation at a very low spinning speed (Ullmann's Encyclopedia of Industrial Chemistry, 5th Ed., Vol. AlO, Fibers, 3 General Production Technology, pp.550-561). The present invention discloses particles that are economically efficient, in addition to the corresponding high-capacity melt-spinning, and especially in the case of fiber development, and in the case of significant stretching on the fiber production line. The fiber manufacturing method of the present invention preferably selects a spinning speed in the range of 800-2400 m / min. Although the spinning speed is not limited by the present invention, when manufacturing partly forward filament yarn (POY), It is best to use a spinning speed of 3000-8000 m / min. The advantages of commercially available polymethyl methacrylate products (DEGALAN® of DEGUSSA Co.) as additives have been proven. Although the high molecular weight DEGALAN® type G8E has a molecular weight of about 126,580 g / mole (average molecular weight measured by the method described below), the results have found it to be very suitable as an additive. In addition to the severe increase in elongation, substances with very high molecular weights can cause mixtures with polyesters to create a large capacity at high spinning speeds. Because it contains a very high molecular weight 9 (please read the note on the back first to write this page)-wiring!

Description of the invention (1) DEGALAN® G8E and poly The blend of ethylene terephthalate (pet) has superior spinning behavior, so it can be assumed that the PMMA type of low molecular weight (such as 20,000-120,000 g / mole) can improve the conventional spinning f . Furthermore, compared with the additive component (thioimidized polymethacrylate) described in European Patent No. 0,631,638 B1, polymethylmethacrylate is relatively cheap and has better availability. Based on the effect of the increase in the amount of stretch, the polymethyl methacrylate of the present invention is suitably a molecular weight (average weight) between 20,000 and 200,000 g / mole. The preferred molecular weight is between 50,000 and 160,000 g / mole, and most preferably between 80,000 and 140,000 g / mole. The molecular weight of PMMA measured by the following measurement method (internal analysis direction No. LCO12 of EMS CHEMIE AG) is: The distribution of the molecular weight and weight average molar mass (Mw) of PMMA is determined by gel dialysis chromatography (GPC). That is, a GPC measurement device having a basic component pump device for liquid chromatography, a chromatography column, and a detector. This measurement method was performed using a Waters Co. type GPC 150A device with an IR detector. A 250 mm x 7 mm (diameter) fourth independent tubing string is connected to one of a series of lengths forming the lm header string. These columns are packed with 10 μπι MERCK LiChrogel® and combined with PS4000, PS400, PS20 and PS4 (referred to as pore size) to fill four separate sections so that each fraction of PMMA molecular weight can be selectively separated . Chloroform was used as a storage solution for PMMA samples and 0.1% 1,2-dichlorobenzene was used as a buoy. Chloroform with a flow rate of 1 ml / min was used as the eluent. In order to make 10 (please read the note on the back to write this page first); Thread-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) Printed by the Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs 490513 A7 5280pif.d〇c / 〇〇8 ηγ 5. Description of the invention (2) Prepare samples, place each 50mg PMMA sample in a 20mL sealed glass container, then fill it with a labeled storage solution, and stir until completely dissolved. First, at least 5 standard units of PMMA need to be prepared in the same way, which uses POLYMER LABORATORIES Co. to measure the molecular weight, and this molecular weight range is 5,720 < MW < 360,000. The measurement of molecular weight is calculated using the standard tritium. Each glass container was injected with 200 µl of sample solution. All processing is performed below. According to the narrow standard of this method, the measurement of tritium (gel dialysis chromatography) is made using GPC software, MILLENIUM (by WATERS). The amount of PMMA mixed is in the range of 0.1-4% relative to the polyester as the fiber-forming polymer. The preferred range is between 0.2 and 3%, and most preferably between 0.3 and 2%. Polymethyl methacrylate as a PET additive can be mixed using, for example, a so-called continuous modification polymer melt (DE 40 39 857 C2) melt conditioning method. The contents of DE 40 39 857 C2 are hereby incorporated by reference. The amount of partial melting that is polymerized by condensation or remelted is separated from the main molten main stream. This part of the tributary enters the side stream extruder, and is then mixed in the form of granules and powders, preferably in the form of pearls, and then dispersed. The dispersed and mixed molten concentrate is returned directly to the main melting line and then diluted to the final concentration. In addition to the above-mentioned melt processing method, for example, it can be injected into a main melt stream by a melt extruder to produce a pure amount of added melt.

Description of invention (q) ester) A homogeneous and additive inclusion body provides a relatively aligned mix of ingredients. If PET pellets are used as the starting material and melted in the spinning extruder, you can directly measure the additives (in the form of granules, powders or pearls) used as PET pellets in the spinning extruder. Form) of PMMA. The additives were dispersed in polyethylene terephthalate, and then the molten mixture was spun. Since the melt treatment method facilitates the fine distribution of the amount of molten PET, the pearly PMMA starting form is preferred among the various forms mixed here. In addition, commercial PMMA products are usually easier to obtain in this form. This pearly form is conceivable as a sphere with a diameter of about 0.3 mm, sometimes called a grit. Additives can be used both as a pure matrix and as the main mix. In addition, the remaining added substrates or additives can be shredded and spun at the same time. The polyethylene terephthalate itself contains general additives such as a delustering agent (titanium dioxide), a stabilizer, and a catalyst. The polyethylene terephthalate (PET) or polyester in this application is a polyester containing at least 80% polyethylene terephthalate units, and the largest 20% units, such as diethylene glycol, 1,4-butanediol, or dicarboxylic acids other than terephthalic acid, such as isophthalic acid, hexahydroterephthalic acid, and dibenzoic acid. Polyethylene terephthalate can be selectively modified with a small molar amount of a branching agent having 3-4 functional alcohols or acid groups, such as trimethylpropane, trimethyloletane, pentaerythrite, glycerol, trimesic acid, trimellitic acid or pyromellitic acid. However, in order to modify the dyeing ability, the starting polyester can include (please read the precautions on the back first-write this page) • Thread!

Therefore, dynamic and / or static mixers can be placed directly before the spinning assembly. In the embodiment of the present invention, first, a ready-to-use, dispersed molten mixture that can be produced in any of the mixed variants is spun into agglomerates, rather than spun into fibers. High-efficiency agglomerates can be processed by conventional spinning machines with a melt extruder and spun into fibers or filaments. In this process, secondary processing manufacturers, such as customers of pellet manufacturers, use the polyester of the present invention to modify, without the need to provide conventional spinning machines with expensive measuring and mixing equipment, and without the need to purchase additional separate additive. In this way, for secondary processing manufacturers, all processing is as simple as the same PET pellets. Figures 1, 2 and 3 show cross-sectional images of the REM melt-spun cross-section of the dielectric polymer (PET) according to the present invention. This is the wafer surface in the non-forward direction. In particular, Figure 3 (rod-shaped, lateral cross-section) shows the axial inclusions of the PMMA additive (referred to the fiber axis). The invention is illustrated in detail by the following examples, which do not limit the invention. A conventional spinning machine is, for example, a machine described in Ullmann's Encyclopedia of Industrial Chemistry, 5th Ed., Vol. AlO, Fibers, 3 General Production Technology, pp. 550-561.

The invention is clear (丨 () 1) The results of the spinning test at a take-up speed (Vwick) of 4,950 meters per minute. The spinning temperature range is 208-295 ° C. , Preferably 285QC. The cooled filaments need to be passively cooled, such as DE197 16 394 C1. After the cooling wire spinning step is performed, the yarn ball is guided to a low-temperature godet-duo, and then coiled. The speed of the roller is 5000 m / min, which is the speed at which spinning of each variant except the blank sample "Blank-2" starts. The speed of the roller of the species "Blank-2" (conventional, does not require additives) It is 3225 m / min. The mixed additives are melt-processed (DE 40 39 857 C2), which is usually applied to the melt modification of conventional continuous polyethylene terephthalate condensation polymerization connected to a spinning machine. In order to make yarn balls, we often use EMS- CHEMIE AG polyethylene terephthalate, also known as GRILENE® M764. The additive used is polymethyl methacrylate from DEGUSSA Co., also known as DEGALAN⑧G8E. Its molecular weight (average weight) is 126,580 g / mol. The concentration is 0.65- (K90wt%. The average lateral diameter of the polymethyl methacrylate inclusions is less than 400nm (see Figures 1, 2, and 3). The spinning behavior is good. Only the entire silk cake is manufactured (Spool). Table 2 shows the textile information of the textured yarn. The quality information achieved by the modified polyester is consistent with good, conventionally manufactured yarns. However, when there is only general The POY yarn is spun at a spinning speed of about 3200 m / min, and the productivity distribution of its spinning machine is very large.
